Description

DETAILED DESCRIPTION OF THE INVENTION <Purpose of the Invention> Industrial field of application The present invention relates to an automatic filling and packaging method, and more specifically, in a pillow packaging in which a cylindrical film is filled with sealed meat such as sausage and sealed. By supplying water to the tubular film filled with the kneaded meat, it is possible to smoothly perform the ironing by the ironing member, and it is possible to continuously ultrasonically seal the kneaded meat in the tubular film while excluding the kneaded meat. This relates to the automatic filling and packaging method.

In the following, the term “condensed meat” includes animals and all those containing these, and is mainly composed of animal meat such as beef, pork, and lamb, cod, pollack, salmon, seafood such as shellfish, etc., if necessary. It includes those kneaded with other ingredients and seasonings.

Conventional technology Conventionally, the condensed meat can be stored for a long period of time by filling a plastic film having heat resistance and gas barrier properties such as a vinylidene chloride film and sterilizing under pressure,
Widely used as so-called sausage.

As a packing method of these kneaded meat, a heat-resistant, gas-barrier flat film is formed into a tubular film by means such as backing, and the kneaded meat is filled in this film, and the filled tubular film is rolled. There is a rocket package that is compressed with metal and then clipped with metal. Although sausages packaged by this method are retort-processed to be commercial products, since metal is used for clips, metal detectors cannot be used for foreign material inspection, and because the seal is not perfect, it lacks safety etc. There's a problem.

Therefore, there is a pillow package that is an improved version of this rocket package. That is, the pillow package is formed by continuously forming a tubular film from a flat film, filling the tubular film with kneaded meat, and further squeezing the tubular film filled with the kneaded meat with an ironing member. This is a method in which a portion where meat is excluded is fusion-sealed by ultrasonic waves (Japanese Patent Laid-Open No. 62-251306).

This method eliminates the kneaded meat in the seal part almost completely, and does not heat the tubular film of the seal part externally, and it is fusion-sealed by ultrasonic waves, and the completeness of fusion and the appearance of the seal part are good. There is an advantage that it is possible to exert the nature. However, when ironing a tubular film filled with meat, and also when ultrasonically sealing, because the lubricity of the tubular film is not sufficient, contact, movement, etc. of the ironing member and the ultrasonic generator, It may damage the tubular film. Also, the meat may be discharged from the tubular film. Burrs are generated when the kneaded meat and the cylindrical film are attached to the surface of the cylindrical film to form the cylindrical film. If the burr remains attached to the tubular film, the functions of the ironing member and the ultrasonic generator are gradually deteriorated when the ironing member and the ultrasonic generator are operated for a long time, resulting in a problem that product quality and productivity are deteriorated.

In order to solve this, the device is stopped and the work of removing the adhered substances is being performed, but the operation is stopped, which causes a decrease in productivity and also deteriorates the quality of the condensed meat in the pillow type packaging device. It is not preferable.

In summary, as described above, in the conventional example, the pillow packaging of the condensed meat has been developed, but only the degree described in JP-A-62-251306 has been proposed. Therefore, with respect to the deposits generated in the seal portion of the pillow package, the property of the tubular film and the ironing member,
No consideration has been given to ultrasonic sealing devices, etc., and no pillow packaging method for improving the product quality and productivity has been proposed.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention aims to solve these problems. Specifically, in the conventional example, the tubular film filled with the meat is not sufficiently lubricious, During contact movement of the sound wave generator, the cylindrical film is damaged, and the boiled meat discharged from the damaged part adheres to the ironing member and the ultrasonic wave generator when the cylindrical film is formed, producing sausage and the like. It is difficult to carry out the above continuously for a long time, and further, it is intended to solve the problems such as the pillow packaging method for such meats which has not been sufficiently researched and developed.

<Structure of the Invention> Means for Solving Problems and Actions Thereof That is, according to the present invention, a tubular film is formed from a flat film, and the tubular film is filled with kneaded meat or the like. In a pillow package that ultrasonically seals the tubular film filled with, while the water is supplied to the tubular film filled with the kneaded meat and the like, the ironing member causes the kneaded meat and the like in the tubular film to move in the axial direction of the tubular film. It is characterized in that the tubular film of the removed portion such as the meat and the like is ultrasonically sealed by sliding the tubular film onto the tubular film.

Therefore, the structure and operation of these means will be described more specifically as follows.

First of all, the inventors of the present invention attach the meat or the like to the ironing member or the ultrasonic wave generator, etc. to lubricate the tubular film when the ironing member or the ultrasonic wave generator contacts or moves. Focusing on the fact that there is a problem with the property, we improved the lubricity of the tubular film, searched for a food hygiene product that can be used, and studied the application conditions. The present invention has been established based on the finding that it is sufficient to continuously supply water to the cylindrical film and bring the tubular film into contact with the ironing member, the ultrasonic generator, and the like via water.

Further, it is configured to generate an ultrasonic wave when it comes into contact with the pedestal 16.

As above, each configuration of the pillow type packaging device has been described.
Furthermore, in the present invention, after filling the cylindrical film 10 with the meat paste 14, the cylindrical film 10 is guided by the guide roll 18 and moved downward while being washed with water supplied from the water supply pipe 19. It is configured to be.

Next, a method for packaging condensed meat using the packaging apparatus described above will be described with reference to FIGS. 1, 2 (a), (b), (c) and (d).

As shown in FIG. 1, a flat film 9 is wound around the film guide 5 of the tubular film forming mechanism 1 from a flat film supply roll 8 and is fed back by a sealer 7 while being fed by a feed roll 6. Then, the tubular film 10 is formed by sealing the above, and, on the other hand, the above-mentioned tubular film 10 is filled with the above-mentioned tubular meat 10 via the above-mentioned pasty meat feeder 13 and the above-mentioned pasty meat feeding cylinder 11 of the pasty meat filling mechanism 2. As a result, the cylindrical film 10 filled with the meat 14 forms a water film on the entire surface by the water supplied from the water supply pipe 19, and the ironing mechanism 3
Sent continuously to. Then, the meat meat 14 in the cylindrical film 10 is squeezed by the ironing mechanism 3, and the meat meat 14 is squeezed by the ultrasonic generator 4 and the cylindrical film 10 at the portion where the meat meat 14 is removed is fused. Sealed.

In addition, ironing the tubular film 10 with the ironing arms 15 and 15,
When the meat is eliminated and sealed by the ultrasonic generator 4, the water on the surface of the tubular film 10 is sprayed by the vibration of the ultrasonic generator 4 to cool the ultrasonic generator 4 and cool the meat. To prevent the adherence of burrs and prevent the formation of burrs.

Next, the ironing and fusing operation will be described with reference to FIGS. 2 (a), (b), (c) and (d).

First, as shown in FIG. 2 (a), when the tubular film 10 filled with the kneading meat 14 is transferred between the ironing arms 15, 15 and the pedestal 16, as shown in FIG. 2 (b). Nigiri arm
Squeeze member 1 by moving 15 and 15 toward each other
Both 7 and 17 are brought into contact with each other, and in this state, they are moved in the direction of the pedestal 16 and pressed against the pedestal 16 by the ironing members 17, 17 to fill the tubular film 10 filled with the kneaded meat 14 in the tubular film 10. When the boiled meat 14 is removed vertically, the pedestal 16 and the ironing members 17, 17
Only the tubular film 10 is left in between.

Next, as shown in FIG. 2 (c), the ironing arms 15 and 15 are moved vertically with respect to the axial direction of the tubular film 10 so that the ironing members 17 and 17 are separated from each other. As a result, the ironing members 17, 17 are slid, so that the meat 14 in the tubular film 10 is squeezed by the sliding distance of the ironing members 17, 17. At this time, the ironing arms 15 and 15 are moved a little longer than the top length of the pedestal 16 to remove the ironing members.
17 and 17 are moved to positions slightly lower than the shoulders at both ends of the pedestal 16.

On the other hand, since the ironing arms 15 and 15 press the tubular film 10 with a predetermined pressing force in the direction of contacting the pedestal 16,
The meat 14 can be sufficiently removed over the length of the top of the pedestal 16, and the ironing members 17, 17 are sandwiched by the tubular film 10 with both shoulders of the top of the pedestal 16.

Further, as shown in FIG. 2 (d), the ultrasonic wave generator 4 is moved so as to contact the pedestal 16 to generate an ultrasonic gun. This supersonic gun locally generates heat by mechanical vibration caused by the supersonic gun and the tubular film 10
The meat remaining inside is completely removed, and a fusion seal is made on this portion.

When the fusion seal is completed in this way, the ironing mechanism 3
Also, the ultrasonic generator 4 is moved in the opposite manner to the above, and the second
It is returned to the position shown in FIG.

Hereinafter, by repeating the operations shown in FIGS. 2 (a), (b), (c) and (d), fusion sealing is performed at each predetermined position of the tubular film 10 filled with the kneaded meat 14 and kneaded. meat
14 can be packed continuously.

As described above, according to the embodiment of the present invention, the ironing members 17 and 17 are provided while supplying water to the tubular film 10 filled with the meat paste 14.
By squeezing the meat 14 with the slide method,
Since the ultrasonic sealing is performed in a state in which the remaining kneaded meat 14 is removed, the deposits such as burrs always flow together with the supplied water and impart lubricity to the tubular film 10. State and ironing member
The tubular film 10 will not be damaged even if the 17 and 17 are operated with a strong pressing force or slid. That is, since the condensed meat 14 can be prevented from being discharged from the tubular film 10, the above-mentioned adhered matter does not occur. example,
Even if deposits are generated, the ultrasonic gun generated from the ultrasonic generator 4 scatters water present on the surface of the tubular film 10 in the form of a spray, and this water easily adheres to the ultrasonic generator 4. Will be removed. Therefore, a product having a high sealing strength can be continuously and effectively obtained, and a product such as sausage can be obtained by retort-treating the product.

Although one embodiment of the present invention has been described with respect to the method of packing while feeding the mixed meat 14 in the vertical direction, it may be carried out by the method of packing while feeding it in the horizontal direction. In this case 14
Water may be constantly supplied from above the sealing portion of the tubular film 10 filled with.

Examples Below, examples will be described.

Example 1. Comparative Example 1. Using the apparatus shown in the block diagram of FIG. 1, pillow packaging was performed while supplying water so that the surface of the sealing portion of the tubular film was always covered with water.

The film is 15μm stretched nylon film (ONY) and 60μ
A two-layer laminate of m casting methylene polypropylene film (CPP) was used to form a tubular film with the CPP inside. Sealing conditions are frequency 2KHz, voltage 100
V, output 600 W, ultrasonic wave 0.3 sec, pressing force 5 kg, tubular film 1 sec. As a result, the peel strength of the fusion-sealed portion was 5.0 kg / 15 mm. In addition, this operation 1
It was carried out for a month, but no abnormality was found.

For comparison, the pressing force was 3 kg without supplying water to the tubular film.
The peel strength was 4.0 kg / 15 mm in the same manner as in the example except that the above was used. In addition, the pillow packaging operation required cleaning of the ultrasonic generator every week.

<Effects of the Invention> As described above, the present invention forms a tubular film from a flat film, fills the tubular film with kneaded meat and the like, and provides a tubular film filled with the kneaded meat and the like. In a pillow package for ultrasonic sealing, while removing water by supplying water to the tubular film filled with the kneaded meat or the like, sliding the kneaded meat or the like in the tubular film by an ironing member in the axial direction of the tubular film, This is characterized in that the cylindrical film in the portion where the meat and the like is excluded is ultrasonically sealed.

Therefore, it is possible to maintain a high seal strength as in the conventional example, and since water is constantly supplied to the surface of the tubular film in the sealing portion, the pressing and moving of the ironing member is smoothly performed, and the tubular shape is improved. Since the film is not damaged, it is not necessary to wash the ironing member, the ultrasonic generator, etc., and a product of good quality can be efficiently obtained.
